URL Alias is a free Chrome add-on developed by Merve Sahin. It falls under the category of Browsers and is specifically categorized as an Add-ons & Tools. This program allows users to create short aliases for URLs, making it easier and faster to access their favorite websites.

With URL Alias, users can create aliases in the same way they create bookmarks, using a button on the address bar. These aliases are prefixed with a slash (/) when entered in the address bar. This feature is especially useful for frequently visited websites, as it eliminates the need to type in the entire URL every time.

In addition to creating aliases, users can also view and edit their existing aliases by opening the extensions popup in the address bar and clicking on 'My aliases'. This provides a convenient way to manage and organize the aliases for quick website access.

URL Alias is a simple yet powerful tool for Chrome users who want to streamline their web browsing experience. By providing a way to create and manage aliases for URLs, it offers a faster and more convenient way to access websites directly from the address bar.
